Simulate a Spring compressing

[mchattie]

Is there anyway to simulate a spring compressing in DMU Kinematics?

I have the spring, which will be compressed by two flat plates - but I want Catia to simulate the compression of the spring on the screen.

Is there a special Joint I use for that?

Thanks

James

Spring Compression is not kinematics, it's Dynamics. CATIA cannot do it, although there are a couple of CAA applications that will - one from LMS and one from MSC.

There is a work-around for CATIA that involves parametrics and assembly constraints, instead of Kinematics. Essentially, you create some Assembly Level parameters, associate them to your constraints as well as to your spring, and change the values of the parameters. As your assembly updates, so will your spring.

Many people simulate the spring compression by faking it. Make two ends of the spring, and then slide them over each other to make the ends move.
